Betulin (CAS: 473-98-3) inotorwa kubva kumakwati emuti chena webirch, iyo yave ichizivikanwa kubva muzana ramakore re18 uye inotsanangurwa nemakemikari.Betulin yakawanikwa neGerman-Russian chemist Johann Tobias Lowitz.Aive musayendisiti wekutanga kudzidza uye kuratidza betulin, uye mukuita yaive imwe yekutanga kuparadzanisa inoshanda chirimwa chinosanganisa.Betulin chinhu chechirimwa chakachena chinopa birch bark ruvara rwayo ruchena.Betulin inodzivirira miti yebirch kubva kune zvakatipoteredza, senge tembiricha yakanyanyisa, kuputika kwezvipembenene uye nemwaranzi yezuva.
Betulin iwhite crystalline powder, inonyungudika mudoro, chloroform uye benzene, inonyungudika zvishoma mumvura inotonhora, petroleum ether.
Physiological mhedzisiro ye betulin
1. Betulin nezvinobuda mairi zvakaratidza kugona kukuru semishonga yebhayoloji muHIV nekurapa gomarara.Vanoshanda nekukanganisa nhanho dzekupedzisira dzehupenyu hwehutachiona uye zvine chekuita nekupinda kwehutachiona uye kukura nekukura.
2. Mishonga inorwisa bundu inoshanda, iyo inokonzeresa zvakananga mamwe marudzi emasero ebundu kuti atange kuzviparadza apoptosis zvirongwa, uye anogona kunonotsa kukura kwemarudzi akati wandei emasero ebundu.
3. Betulin inogona kuderedza kudya-induced kufuta, kuderedza lipid content mu serum uye tishu, uye kunatsiridza in-sulin k senitivity.
4. Vane zvinyoro-anti-inflammatory properties pamatunhu akakwirira, uye maitiro avo e-anti-inflammatory anonyanya kukonzerwa nekudzivirira kwemaitiro asina-neural gene.

6. Mukuwedzera, Betulin ine anti-inflammatory, anti-viral, inhibiting protein dissolution mubvudzi fiber, inovandudza kupenya kwebvudzi rakakanganiswa, nekusimudzira bvudzi kukura.Betulin inogona kushandiswa mune zvekudya, zvizorwa uye maindasitiri emishonga.
Pharmaceutical industry:
Betulin inonyanya kushandiswa semushonga wepakati, uye Betulin nezvinobvamo sebiological agents zvakaratidza kugona kukuru mukurapa HIV negomarara.Panguva imwecheteyo, inoshandiswa kune antitussive uye expectorant, kurapwa kweallergic rhinitis, kushaya hope, kuora mwoyo, nezvimwewo.
Indasitiri yeChikafu:
Pane zvidzidzo zvinoishandisa sekuchengetedza mune zvigadzirwa zvenyama.
Cosmetics industry:
Iyo inhibitory mhedzisiro yeBetulin pane collagenase chiitiko uye kuwanda kwemasero eganda kunoratidza kuti ine yakasimba anti-kuchembera mhedzisiro uye inogona kushandiswa kugadzirisa ganda, kutsvedzerera ganda, uye kudzivirira ganda rakapwanyika.Iyo zvakare yakanaka yekunze rubatsiro rwekupinda.
Parizvino Betulin inowanikwa kunyanya kuburikidza nekutorwa kwakananga, uye kunyanya kuburikidza nekugadzirisa reflux kubviswa uye recrystallization kucheneswa Kunyanya: 1. Bvisa betulin kubva kune ethanol solution.Mushure mekupisa reflux inenge 5h, iyo yakatorwa inosvina distillized uye recrystallized ne ethanol kwe2 kusvika ku3 nguva ne ethanol kuti uwane crude product ye betulin.2. Chigadzirwa chisina kuchena chakaitwa zvakare kubva kune methanol / chloroform (1: 1) (yose 80g crude product inoda 300mL methanol / chloroform solution) .Musanganiswa unobvumirwa kumira usiku hwose uye wozosveta sefa kuti uwane chena tsono-yakafanana betulin.3. Ultrasonic kurapwa kwe 20min apo refluxing inoitwa, uye kukohwa kwekuchera uye kuchena kwechigadzirwa che betulin kunogona kuvandudzwa kuburikidza nekuparadzwa kwe bark sangano.4. Mamiriro akanyanya kunaka e-supercritical CO2 fluid extraction ndeaya anotevera: chiyero chekugadzirisa chaiva 115mL / (g birch bark powder);kudhonza kudzvinyirira ndeye 20MPa;tembiricha yekubvisa yaive 55 ℃;mvura CO2 kuyerera mwero yaive 10kg/h.
